1，关于eclipse Che
构建工具支持：Ant、Bower、Grunt、Gulp、Maven 和 Npm
支持开发工具链：Code Mirror、Git、Orion、SSH、Subversion
2，安装
首先需要安装docker。使用CentOS7 直接yum安装：启动docker。
yum -y install docker
service docker start
systemctl enable docker
#增加开机启动。eclipse che下载地址：
http://www.eclipse.org/che/
开源的技术发展的真快，已经开始折腾云IDE了。
看看这个是用啥技术实现的。
github项目地址：
https://github.com/eclipse/che/
看了看项目的ide，居然是用GWT开发的。挺怀念的，之前一直研究这个，可惜没有使用上。
各种报错：
!!!
!!! Running 'docker' succeeded, but 'docker ps' failed. This usually means that docker cannot reach its daemon.
!!!
############################这个是因为docker服务没有启动。
执行service docker start，一定要有docker服务。
!!!
!!! This Linux user is not in docker group. See https://docs.docker.com/engine/installation/Ubuntulinux/#create-a-docker-group

!!!!!!
!!! Running 'docker' succeeded, but 'docker ps' failed. This usually means that docker cannot reach its daemon.

############################因为组设置的不对，创建docker用户。
useradd docker
gpasswd -a docker root
sudo su docker
sh bin/che.sh run
!!!
!!! JAVA_HOME is not set. Please set to directory of JVM or JRE.

修改 /home/docker/.bashrc 最后一行增加
#add JAVA_HOME
export JAVA_HOME=/usr/java/default
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
!!!
!!! Che requires Java version 1.8 or higher. We found 1.7.0_75.
!!!
必须安装jdk 1.8
成功启动：

4，总结
eclipse che都已经发布到4的版本了。还没有咋研究呢。
总体感觉上肯定没有本地IDE功能强大。
思路挺好的。可以将docker结合起来，而且还开源，将来做一些云服务，还是挺好的。
由于国内网络问题，没有进入工作界面。
只要有网络的地方，使用浏览器都能让码农干活。
这种项目最好还是不要发明出来的好！！！
